An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

Investigating the rate of reaction between Marble Chips (Calcium Carbonate) and hydrochloric acid Aim. In the investigation I am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small/large pieces of Marble Chips (Calcium Carbonate) and Hydrochloric acid per minute. Hypothesis. The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by

Both Union Carbide and the Indian government had the ethical obligation of non-maleficence; their obligation was to avoid harm to employees of the plant as well as citizens living in Bhopal. Additionally‚ Union Carbide and the Indian government had the ethical obligation to ensure that safety precautions were taken in daily operations of the plant as well as making corrections to known safety deficiencies. The Indian employees had the ethical obligation of fixing the problems that were pointed out

the fateful night of December 2‚ MIC gas began escaping from Tank 610 around 10:30 p.m . Gas was released when water interpolated into one of the storage tanks late that night . The water could not have got into the tank on its own . Union Carbide Corporation investigators have found new evidence pointing towards a theory that the tank was purposely sabotaged by a employee . Witnesses in the plant that night claim that an employee working that night was inraged due to a recent change making

Class 4 – Flammable Solids Division 4.1 – Flammable Solids are: • Wetted explosives that are Class 1 explosives when dry‚ that are sufficiently wetted to suppress explosive properties. • Self-reactive materials that are thermally unstable and can undergo strong exothermic decomposition even in the absence of oxygen. Readily combustible solids that can cause fire through friction‚ such as matches. Powdered‚ granular or pasty materials must be classified as Division 4.1 when the time of burning of

University Introduction Diamond is the hardest material known to man‚ in this day and age. Typically‚ diamonds have been known to demonstrate hardness values up to 12000 HV (Vickers Hardness) or approximately 100HRC. Diamond-coated Tungsten Carbide tools have demonstrated improved machining characteristics over coated tool steels commonly used today. With the increased use of composites‚ ceramics‚ and other ultra-hard / lightweight materials in numerous industries‚ diamond-coated machine tools
